It will be evident that while l have r "i in the drawings un operative device. wll many changes might be made in size, sin ie and arrangement of part-s without departing materially troni the spirit orf my invention` and l wish, therefore. to ha 'e my drawir regarded as in a sense diagrammatic.

The use and operation of niy invention are as follows:

I provide a combined draw bar and trailer element for a two wheel tractor, one tunc` tion being to perinit the attachment to the tractor ot the load. and particularly of agri4 cultural implement-s, plows and the like, drawn thereby.

Another function is the use ot the trailer as a support for the tractor when it is without a load, since obviously the two wheel tractor type requires an additional support to prevent its tilting over.

When the tractor is `in use and is drawing: a load the iniplement or vehicle drawn is secured to the -outer ends of the A l'ranies in any suitable way. The unbalanced weight ot the tractor being to the rear when it is moving 'forward there is a downward pres sure through the A 'trames and on the supporting wheel or the implement or vehicle drawn. The height of the draw-bar trailer or its angular relation to the tractor may be adjusted, of course, by adjustingr the lengths of the various frame men'ibers, the rear ends of the frame at the point of attachment to the vehicle being thus raised or lowered. The rearward tilting of the tractor is thus limited by the height of vehicle or impleA ment, and the connection ma;Y be adiusted to suit such heights. The rearward tilting); oi the trailer is also limited bv the supporting wheels which inav also be adjusted or swung entireli..7 out ot contact with the ground when desirable In the position shown in Figure l the uriner and lower frames ot the draw-v ber trailer together form right angle triangles, with the risrht angle adjacent the at taehment ot the lower frame members to the tractor. This angle varies` of course, with the adiustment oi the height of the vehicle or iinnlernent, but in any Case the two frames are rigidly limited against movement in a vertical plane. but they tilt freely about a Vertical axis to permit the tractor to turn. The lever A8 also permits the oscillation ot the pivot point of the upper trame member, which compensates for the unevenness of the ground, as where one plow or wheel, for eX- ample` is several inches higher than the other, and thus lifts one arm of the trailer traine in relation to the other. The connes tien between the fixed lug A1 and the meine i if is preferably fairly lo0se,'in orc to pre rent bending or breakage because ol' lateral tilting of the lower A Atrame.

l'i'vlien the trailer is being` used to dranY implements the whe ls are normally lifted out or' contaet with the ground, the axle and crank being swung to the position shown 'v dotted lines in Figure l, and the links DT )Qing secured to the lugs D, ns shown in The seat of the operator is adjustably supported on .the axle, the seat supporting spring` resting on a bearing which is slidably und rotatably mounted in relation to the said axle.

lihen the implements have been disconnected, the axle is swung,` to the full line position shown in figure l, and the wheel then contacts the =ground, the axle being kept in this position by connecting the links D7 with the lugs D5. rlhe trailer in combination with the two wheel tractor makes, to all intents and purposes, a four wheel tractor, and the tractor may travel under its own power, without other support.

The width of the base of the 'frame maj.' be adjusted by means oi links E4, which a in adjustable connection with the side traine members B, and the connecting` links also permit the seat to be accuratelycentered in the middle of the device, if that is neeessary.

he sleeves D and E are slidable on the axle D, thus making both these adjustn'ients easy.

Y*."Vhile l have illustrated a draw bar trailer which is particularly adapted for use with a two-wheel tractor, it might alsobe used with the three or four wheel type if desired. Although it is particularly adaptable for drawinel agricultural instruments, it may also be used to draw wagons or other vehicles.
